The holy text of Islam is called the Qur'an (also spelled Koran). The word Qur'an comes from the Arabic word iqra (to read), and is a noun that literally means “the Reading.” Revealed verse by verse to Muhammad over a period of twenty-three years, the Qur'an is the center of Muslim life. The Qur'an was revealed in the Arabic language and is preserved in its original form, although translations of the meaning have been done into other languages. Through stories and parables, direct instructions and warnings, the Qur'an gives a universal message of belief in One God and in the guidance He has sent through time.
